IMPROVEMENT IN MACHINES FOR MAKING PAPER COP-TUBES FORSPINNING-MACHINES.

Specication forming part oflhettersrlratent No. 50,204, dated September26, 1865.

To all whom it may concern:

Be it known that I, WILLIAM J. INNIS, of

Providence, in the State of Rhode Island, have invented a new and usefulMachine for Making Paper Cop-Tubes and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspeciiication, in which- Figure l is a plan; Fig. 2, a vertical sectiontaken at the line A a of Fig. l 5 Fig. 3, an elevation of the front endof the machine, with the brush and its appendages for turning down theend of the paper and for knocking off the formed paper tubes removed 5Fig. 4, an elevation of the said brush with its appendages; and Fig. 5,a separate view of the nippers, with the mechanism by which they areoperated.

The same letters indicate like parts in all the figures.

In spinning cops which are to be taken from the spindles andtransf'erred to shuttles it has long since been found convenient andeconomical to slip a short paper tube onto the lower part of thespindle, and the lower part of the cop in spinning is formed on thispaper tube, so that the tube forms part of the cop, and is drawn fromthe spindle with it, and prevents the disturbance ot' the threads andthe production of waste in transferring the cops from the spindles tothe shuttles. These paper cop-tubes have heretofore been made by hand atconsiderable expense, and my said invention relates to machinery formaking them.

In the accompanying drawings, a represents a suitable frame. 'Ihe paper,of the required width, is, for convenience, wound on a drum, to betherefrom presented to the machine. The paper so presented, or in anyother suitable manner, passes down a channel-way, b, which guides it tothe bite of a pair of rollers, c d. The shaft of the lower roller, c,carries a cogwheel, e, which receives an intermittent motion from acogged sector, f, on the main drivingshaft g, driven by any suitablemotor, thelength ofthe sector being such as to give the roller-c at eachoperation the requisite range of motion to feed or advance the length ofpaper required for making one cylinder, and then to let it stop untilthe cylinder is completed.

The upper roller, d, is a smooth cylindrical pressure-roller, borne downby rods h h, having helical springs or equivalent means for making therequisite pressure to insure the feeding in of the paper. The lower partof the roller c runs in paste or other suitable cement contained in avat,t', and its periphery is gro'oved, the better t0 take the requiredquantity of paste, carry it up, and apply it to that surface of thepaper which passes in contact with it. From the feed-rollers the stripof paper passes to and over a distributing-rollenvj, covered with clothor other equivalent substance, and on its way to this roller it passesunder a balance-bar, 7c, which keeps it smooth and even. This bar is onarms l L hung on pivots, one of them having a weight, m, which nearlybalances the bar, that it may make but slight pressure on the strip ofpaper 5 and from the distributing-roller the paper passes over a table,a, with sides which act as guides to keep it in line. Thedistributing-roller j turns in opposite direction to the feed motion,and receives this motion by a crossband, o, from a band-wheel,p, on theshaftof the feed-roller c and while the distributing-roller rotates, thebetter to distribute the paste on the under surface of the paper, itvibrates endwise, which motion it receives from a cam-groove in theperiphery of a wheel, q, on its shaft, the said cam-groove run ning on afixed stud or pin, r, attached to the frame. As the forward end of thesheet of paper is advanced a short distance beyond the front end of thetable a it is griped a little back of the forward end by a pair offeeding-nippers,s, attached to the upper part of a sliding frame, t,composed, for convenience of construction, of a vertical bar, t, and twoparallel horizontal bars, u u, which latter are iitted to slideaccurately but freely in holes in two standards of the frame a. One ofthese bars has a helical spring, c, wound around it, thetension of whichforces and keeps the end of the bar provided with a frictionrolleragainst the periphery of a cam, w, on the main driving-shaft, and theform of this cam,

as represented, is such as to cause the nipper to be moved back at theproper time to gripe the paper, and then to be advanced to present theend of it to the mechanism which forms the cylinder.

The upper jaw of the nippers is permanently attached to the bar t of thesliding frame, and

thelower jaw is pivoted in a mortise through the said bar, and extendssome distance beyond the bar to form a handle by which to open and closethe nippers. They are closed by the tension of a spring, w, and openedby a wedge, y, which projects from that part of the main frame in whichthe machinery for forming the cylinders is mounted, so that as thenippers approach this part of the machinery the wed ge y enters betweenthe two nippers and depresses the lower jaw to liberate the paper, andas they must remain open during their back movement preparatory totaking a fresh gripe, they are held open by a spring-catch, z, whichsnaps under the handle when the lower jaw is depressed by the wedge y.At-the end of the back movement the lower jaw is liberated to gripe thepaper by the spring-catch z striking a stop, a.

' The paper tubes are formed on a mandrel, b', which is mounted torotate and slide endwise in standards c d', and when rotating thatportion of its length on which the paper is rolled up extends beyond thestandard c to a .slight socket in a third standard, e. The other end ofit is adapted to slide in and is feathered to a pinion, f', by which itis rotated, the said pinion receiving motion from a like pinion, jz, ona parallel shaft, g', mounted below it in the three standards c d e; andthe pinion f2V receives motion from a cog-wheel, 7L', on a shaft, fi',mounted in the standards c d, and this shaft carries a cone of pulleys,j', driven by a band, k', from a cone of band-wheels, Z, on the maindriving-shaft.

Above the mandrel there is a fluted roller, m', to make pressure on thepaper as it is being wound upon the mandrel. The journals of thispressure-roller are fitted to boxes which are adapted to slide in thestandards c e', and are borne down to make pressure by rods a n',providedwith springs o 0 or ,equivalent weights. This pressure-roller isrotated in an opposite direction tothe mandrel by a train of pinions,p qr', the latter being on the shaft g', before described. As the nippersadvance and present the end of the strip of paper it is griped in thebite of the mandrel and pressure-roller and drawn in between, and as itprojects beyond them it is bent down to make it wind around the mandrelby the rotation of a brush, s', mounted in a frame, t', and whichreceives rotary motion from a belt-wheel, u', on the main shaft, whichdrives a small shaft, fr', which in turn drives the brush by a band, w.So soon as the requisite length of paper has been supplied, and justbefore the rolilng up on the mandrel is completed, the required lengthof paper is cut off by a pair of shears,

au', placed between the mandrel and the table n. The two blades oftheshears are pivoted to a standard, y', and their handles z z are drawntogether to close the shears to cut off the paper by a helical spring,a2, and they are opened immediately after and kept open until the nextcutting operation by an external andk an internal cam, b2, on the shaftc2, which receives motion from the main driving-shaft by bevelcog-wheels d2. There is a stop, e2, between `the two handles z z tolimit the closing of the blades. (See Fig. 1, and shown by dotted linesin Fig. 8.)

I prefer to serrate the cutting-edges of the shears, as that leaves theedges/6i' the paper in'a better condition to paste down than ifcutsmooth. After the winding has been completed the mandrel is drawn out ofthe paper tube so formed, and that is effected by a lever, f3, whichvibrates on a fulcrum-pin at g2, its upper end being forked to embrace acollar, 11.2, on the outer end of the mandrel, and its tailend i2 beingacted upon at the proper time by a tappet-pin, jz, projecting from theface of a wheel, 7a2, on the shaft c2, before described. As the mandrelis drawn out the face of the standard c acts as a stop to prevent theformed paper tube from following it but as the formed paper tube, thusliberated by drawing out the mandrel, is liable to adhere to the flutedpress-` ure-roller, it is necessary to knock it off before the mandrelis forced back to its workin g position by a spring, l2, which bearsagainst its outer end. The tube is knocked off by the rotating-brush,which for this purpose has a reciprocating motion from and toward themandrel. For this purpose the frame t', which carries the brush, ismounted atits lower end on the shaft o', so that it can vibrate thereon.It

is forced toward the mandrel by the tension of ya spring, m2, (see Fig.4,) and it is moved back by a lever, n2, which receives motion for thatpurpose from a cam-groove, o2, in the periphery of the wheel k2 on theshaft c2, before described. By this means, at the time the mandrel isdrawn out of the tube, the cam-groove o permits the brush to be forcedby its spring against the formed tube to knock it off and into asuitable receptacle, completed.

It Will be obvious to any competent machinist, from the foregoing, thatsome parts ofthe said invention may be dispensed with bysubstitutingequivalents, and, therefore, I wish it to be distinctly understood thatI do not limit my claim of invention to the employment of all theabove-described parts in connection, nor to the specially-described modeof construction, as this may be variously changed, so long as the modeof operation is retained.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination ofthe rotating and sliding mandrel with thepressure-roller, su b tially as described, for rolling up anddischarging the tubes, as set forth.

2. The combination of the rotating and slidv ing mandrel andpressure-roller with the reciprocating motion of the brush, orequivalent therefor, substantially as described, for discharging thepaper tubes when completed.

3. The combination of the rotating mandrel and pressure-roller to rollup the paper with the rotating brush, substantially as described,

whereby the end of the paper, when introduced, is caused to lap aroundon the mandrel, as set forth.

4. The reciprocating nippers, in combination with the rotating mandrel,substantiallyas described, and for the purpose of properly presentingthe aber to the mandrel, as set forth.

5. The combination of the shears or the equivalent thereof,substantially as described, to cut 0E the length of paper requiredforeach tube, with the feeding mechanism for moving the sheet of paper,and the mandrel' for Winding up the paper, as set forth.

6. The combination ofthe rollers for feeding the paper and applyingpaste thereto, the Vioff the length of paperrequired for each roll,
